C90500 Tin Bronze Alloy
C90500 Tin Bronze is a cast bronze alloy with high tin content. It is very durable and good in high-load and low-speed applications.
It has a high resistance to corrosion from steam and saltwater. So, it works well for steam fittings and marine applications. Other applications include:
- Bronze Bearings
- Bronze Bushings
- Bronze Gears
- Bronze Pump Impellers
- Bronze Pump Bodies
- Bronze Steam Fittings
- Bronze Valve Components
Diversified Bronze has solid and cored bronze bars in 144" lengths. Other lengths and non-standard sizes are available.
Technical details
C90500 is made up of 88% copper, 10% tin, and 2% zinc. The best welding techniques include:
- Brazing
- Carbon Arc
- Coated-metal arc
- Gas-shielded arc
- Oxyacetylene
- Soldering
